the outer faces of the ends of the casing engage the parallel faces ofthe ribs of the castmg.

The larger telescoping member 1 is pro vided at its upper or surface endwith suitable projections 4:, designed to engage a looking latch orplate 5, carried by the cap or cover 6. The latch 5 is rigidly securedto the cover 6 by fitting into a recess 6 thereof on To all whom it mayconcern:

Be it known that we, J OSEPH RIDDELL and JOHN J. MADDEN, citizens of theUnited States, residing at Sharon, Pennsylvania, have invented certainnew and useful Improvements in Service-Boxes for Conduits, of which thefollowing is a specification.

Our invention relates to service cockboxes, as employed in connectionwith gas and water distribution or the like, and is designed chiefly togive the most convenient access,'to I cook. Also to protect the same andavoid danger of displacement of the parts by frost or temperaturechanges. In boxes of this type, heretofore used, it has been dillicultfor the operator, as a rule, to locate the valve nut with a long key,but in I our device this (lilliculty is reduced toa minil mum, as acentral position of the stop cock, in relation to the exposed box isassured.

The invention consists in the novel arrangeinent and combination ofparts hereinscrew 7. When necessary, the cover, 6 may be easily removed,with a suitable key, by iving a quarter turn thereto in the properirection. The member 1. is also provided with brackets 8 to insureagainst any possible dislodgment of the same, these brackets orextensions being embedded in the ground.

From the foregoing descri tion it will be clearly understood that theevice is simple in cnstruction, therefore comparatively- 1nexpensive tomake, and by it's use the surface box is connected with the casting or'base within which the stop cock is centrally held so that the surfacebox is maintained in central relation to the stop cock and by'introducing a long key centrally of the surface box and the extended tubeconnecting the same 1 with the casting, the stop cock may be readily asshown, is composed of a metal l located. All the parts are rigidlysecured totube or the like having telescoping members 1 gether and aremaintained as one body, and 1 and 2, which permit of any desiredvertical temperature changes and frost will not affect adjustment wheninstalling the device. At their relative positions.

We do not limit ourselves to the telescopic construction as it may besometimes more convenient to make the members i and 3 in in the claim:

The casting 3, as shown, is provided with ribs orproi jections extending from its outer periphery at intervals and theseprojections have paralloljvcrtical faces which come in contact with thecorresponding faces on the ends of the yalvc casing and tend to hold thevalve box or casing rigidly in relation to the casting and thus preventany displacement of the stopcock and keep it at all times centrally ofthe casting. This arrangement also permits the assembling of the partswithout change in the l relative position ofthc stop-cock and the lcasting, as the service pipes may be screwed into the valve box orcasing without disarranging-the parts by reason of the fact that JOSEPHRinnELL.
